Abstract Air pollution research and reports have been limited in south Korea, especially in Chung-nam Province located with many coal-fired power plants(18,050MW) with respect aerosol particle number and mass concentration and Chemical compositions.
This study aims to identify the characteristics of Fine Particulate Matters So that we utilized “KEPRI Mobile Lab” to measure, for 15 days (Jan 25 ~ Feb 9) at city of Boryeong KEPRI Mobile Lab consisted of portable aerosol instruments to measure particle number concentration (1nm ~ 20 um), particle mass concentration (PM1.0, PM2.5), organic and element carbon, cation and anion concentration (PM1.0, PM2.5), Various gaseous measurement (VOCs, NOx, SOx and so on) and meteorological measuring instruments all situated on the back seat of 3.5-ton
Although the Measurement campaign was 15 days long, but it provided preliminary information about aerosol concentrations over areas mainly affected by Coal Combustion Gas. We should consider that the presented concentrations reflect on Vehicle and Ship Flue gas.
In this study, we expect to results shows that dramatic increase in the concentration of submicron particle concentrations (PM1.0) is observed because of northwester wind and long-range transport of air pollutants. The diurnal concentration has different peak characterization as time has gone (AM, PM). the results of the m/z 44(CCO+) and OA(organic aerosol) ratio using HR-ToF-AMS means OOA ratio is changed depends of wind directions.
